Systematic review of the values and preferences regarding the use of injectable pre‐exposure prophylaxis to prevent HIV acquisition
Abstract Introduction Pre‐exposure prophylaxis (PrEP) is an important HIV prevention option. Two randomized trials have provided efficacy evidence for long‐acting injectable cabotegravir (CAB‐LA) as PrEP. In considering CAB‐LA as an additional PrEP modality for people at substantial risk of HIV, it…
